There is a reported problem with node, where it will hang inside
block_processor::add_blockingfunction. There might be a few different causes for that, however the aim of this PR is to provide a workaround that ensures the node will be able to recover when that problem happens. There are two main changes:block_processor::add_blocking. The timeout after which an error will be reported can be controlled byblock_process_timeoutconfiguration variable. By default it is set to 15 seconds.background_threadsconfiguration variable. It controls how many background threads to spawn for handling long running node RPC commands (including the "process" rpc). By default it is equal to the number of CPU cores, but can be increased by node operators that need additional resiliency.
